Influence of pre drying treatment on physical properties of carrots
Barroca, Maria João; Sério, Susana; Guiné, Raquel; Correia, PaulaIn the present work, the effect of pre-treatment of ascorbic acid on color changes and texture was investigated during convective hot air drying at 60ºC. The pre-treatments were done at 0.25 % and 1 % of ascorbic acid with treatment times of 60 and 90 minutes. Changes in color and total color difference were evaluated by the CIELab color system and texture of dried carrots was accessed in terms of hardness, sp...
Influence of pre-treatment on some physical-chemical properties of dried carrots
Guiné, Raquel; Sério, Susana; Correia, Paula; Barroca, Maria JoãoIntroduction: Carrot is the most commonly used vegetable for human nutrition and is an excellent source of β-carotene, vitamin A and potassium, and contains cholesterol-lowering pectin, vitamin C, vitamin B6, thiamine, folic acid, and magnesium. Carrots are highly seasonal and abundantly available at particular times of the year. For extending the availability of this root, several preservation processes can be...
